SPARK-CONSUMER.

Specification of Letters Patent.

Patented Sept. 19, 1905.

Application filed April 27 1905. Serial No- 257,654.

A enable others skilled in the art to which it appertains to make and use the same.

This invention relates to spark arresters, and consumers; and one of the principal objects of the device is to provide means for leading the sparks and cinders back into the fire-box by means of the exhaust.-

Another object is to provide simple and reliable means for screening the sparks and cinders from the smoke-stacks and forcing the sparks back into the fire-box by means of the exhaust.

Still another object is to provide means for dividing the exhaust after it has been used for draft purposes and utilizing the exhaust force for carrying the sparks and cinders back to the fire-box.

These and other objects are attained by means of the construction illustrated in the accompanying drawings, in which-- Figure 1 is a longitudinal sectional view illustrating my invention as applied to a locomotive-boiler. Fig. 2 is a top plan view of my spark-consumer. Fig. 3 is a plan view of one of the screens, and Fig.4; is a similar view of another screen and deflector to be used at the base of the exhaust-stack at the front of the boiler.

Referring to the drawings for a more particular description of my invention, the nuis the fire-box of the same. Immediately above the exhaust-pipe 3 is a delivery-pipe 4, which leads up to the smoke-stack 5 at the front of the boiler and is provided at the curved portion with a netting 6, provided with a deflector 7, which serves to prevent thesparks and cinders from passing directly up the smoke-stack.

Referring to Fig. 2, it will be seen that there are two delivery-pipes 4:, of oval contour in plan and extending forward around the dome and sand-box ofthe locomotive, and in said delivery-pipes 4, at a point substantially in line with the steam-dome, a series of wire-netting rings 8 are placed within the delivery-tubes, the lower portions of said rings being open, as at 9, and a return-pipe 10 has its upper flared end secured to the netting rings 8 immediately below theopenings 9 to a receive the sparks and cinders as they are forced by theexhaust through the screens and into the return-pipe. The delivery-pipes 4 at their rear ends curve upwardly, as at 11, and the rear stack 12 is located centrally upon said delivery-pipes to permit the smoke to issue therefrom practically free from cinders or sparks.

From the foregoing it will be obvious that the sparks and cinders, which are usually a source of annoyance and danger, are carried through a delivery-pipe back to the fire-box to be consumed and that the smoke which issues from the smoke-stack is comparatively free from the annoyance of cinders and sparks.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of a this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A spark-consumer for a locomotive comprising a delivery-pipe opening in line with the exhaust, a front stack, a screen and deflector at the base of the front stack, delivery-pipes leading backward and provided with a series of screens therein, said pipes having openings below and a return-pipe inclosing said openings and leading to the fire-box, substantially as described.

2. In a spark arrester and consumer for a locomotive, parallel, pipes provided with an opening in line with the exhaust, a screen covering said opening, a smoke-stack above said opening, a deflector in said screen, a series of screens in the delivery-pipes, said deliverypipes having openings at the screens, and a .IOO

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
